The **HLMP-BB11-R0TYY** is a high-brightness, blue LED manufactured by Broadcom (formerly Avago Technologies). It belongs to the HLMP-Bxxx series, which utilizes Indium Gallium Nitride (InGaN) technology to provide high light output and efficiency. --- ## 1. Key Technical Specifications | Parameter | Value / Description | | :--- | :--- | | **Material** | InGaN (Indium Gallium Nitride) | | **Color** | Blue (470nm Dominant Wavelength) | | **Luminous Intensity** | 310 mcd to 1150 mcd (typical) | | **Viewing Angle** | 15° (Narrow/Directional beam) | | **Forward Voltage ($V_f$)** | 3.2V (Typical) to 4.0V (Max) | | **Forward Current ($I_f$)** | 20mA (Typical) | | **Package Type** | T-1 ¾ (5mm) Standard Round | | **Lens Type** | Blue Tinted, Non-Diffused | --- ## 2. Structural Features * **Package Shape:** The "T-1 ¾" (5mm) through-hole package is the industry standard for indicator lights and signs. * **Lead Frame:** Features longer leads for through-hole mounting on PCBs. * **Epoxy Type:** The non-diffused, tinted lens focuses the light into a narrow 15-degree cone, making it ideal for applications requiring high intensity over a distance. --- ## 3. Application Use Cases Due to its high brightness and narrow viewing angle, the HLMP-BB11-R0TYY is commonly used in: 1. **Variable Message Signs:** Traffic signals and commercial advertising boards. 2. **Solar Powered Signs:** Efficiency allows for lower power consumption. 3. **Status Indicators:** Equipment that needs to be visible in high-ambient light (e.g., sunlight). 4. **Commercial Decoration:** Architectural lighting accents. --- ## 4. Part Number Breakdown (HLMP-BB11-R0TYY) * **HLMP:** High Luminosity Micro-Package (Broadcom series prefix). * **B:** Blue color (InGaN). * **11:** Refers to the specific viewing angle and lens type (15° Tinted). * **R0TYY:** This suffix refers to the **binning** (specific ranges for brightness and color) and the packaging method (e.g., bulk vs. tape and reel).
